J. V. DESMARAIS WINDOW CONSTRUCTION Filed May 21, 1932 2 Sheets-Sheet 2Patented Jan. 10, 1933 UNITED STATES JOSEPH V. DESMARAIS, OF NEWBEDFORD, MASSACHUSETTS WINDOW CONSTRUCTION Application filed May 21,1932. Serial No. 612,803.

This invention relates to a window construction, and its object is toprovide certain improvements by which, a substantially air-tightconstruction can be obtained in a simple manner without the necessity ofusing complicated and expensive parts.

A further object is to provide a construction of this kind which willobviate the common difliculty resulting from the binding or sticking ofthe sash due to dampness and swelling. I

A still further object is to provide a simple construction in that typeof window in which the window frames may be. lowered and tilted inwardlyto make the rear surfaces of the glass readily accessible for cleanmg iv A still further object is to provide a construction which isapplicable either to wood or metal windows and frames and which iscapable of fabrication without the use of any complicated or unusualparts.

-The accompanying drawings illustrate my invention as applied toconstructions made of wood.

In said drawings, which form a part hereof;

Figure 8 is an enlarged fragmentary vlew of the upper end of the frontbead;

Figure 9 illustrates a slightly modified forgn of front head which maybe employed; an

Figure 10 shows a slightly modified arrangement for attaching the frontbead to the frame members.

Referring to the drawings in detail, the window frame of my constructioncomprises side members 10, 10, which, as will be noted, are formed ofplain strips or boards of uniform thickness. A sill 11 is securedbetween the lower ends of the side members 10 and a top member 12 issecured between the upper ends of said side members. A facing orfinishing strip 13 is secured to the inner edge of the side members l0and similar strips 14 may be secured to the rear edges of such members.

Adjacent the rear edge of each of the frame members 10 and secured tothe inner face thereof is a rear bead 15, these beads extending from thetop to the bottom of the frame.

' The outer or upper sash of the window is arranged in front of thebeads 15. Such outer sash includes side rails 16, an upper rail 17 and alower rail 18. Between each of the side rails 16 of the upper sash andthe adjacent bead 15, 1 preferably arrange a resilient strip 19 ofmetal, the inner edge of i which is bent laterally and secured beneaththe inner edge of the beads 15. The strips l9 extend downwardly adistance substantial- 1y equal to the height of the upper sash, and suchstrips form a yielding abutment against which the side rails 16 of theupper sash are pressed, and they also serve to make a tight jointbetween rails 16 and the heads 15.

Between each of the side rails 16 of the upper sash and the adjacentside members 1.0, I arrange a strip These strips extend from the bottomto the top of the frame and are secured to the frame in the mannerillustrated particularly in Figure 5. That is,

the'strips 20 are not rigidly attached to the frame but are preferablyheld in place by screws or other suitable fastening device 21 whichengage elongated openings 22 in the strips 20. By this arrangement thestrips 20 are supported for limited movement toward and from the rearbeads 15. The upper sash is, of course, arranged between the strips 20on opposite sides of the frame.

The lower or inner sash of the window includes side rails 24, an upperrail 25 and a lower rail 26. The side rails 24 of the inner or lowersash are arranged to abut against the front edges of the strips 20heretofore described. In other words, the inner or lower sash 24 iswider than tne outer or upper sash to the extent of the thickness of thestrips 20.

A front head 27 is arranged in front of each of the side rails 24 of theinner sash. The front beads 27 are preferably secured to the framemembers 10 in a manner which will permit them to be readily detachedfrom the side members 10 of the frame. One form of detachable fasteningdevice which I have found convenient consists of what is commonly knownas a snap fastener and which includes an eye secured to one of the partsand a projection secured to the other part adapted to snap into the eye.Such form of fastening means is illustrated at 28. A guide pin 29 issecured in each of the front beads 27, and these are adapted to registerwith openings in the frame members 10 so as to properly guide and locatethe beads 27 when they are snapped or fastened into position. Each ofthe beads 27, at its upper end, is provided with an inclined surface 30and a tongue 31 which cooperate with complementary portions on atransverse head 32 extending across the top of the frame. By insertingthe tongue 31 into the recess provided therefor in the beads 32 andpressing the lower end of the bead against the corresponding side frame10, the snap fasteners are engaged which serve to hold the bead firmlyin position and at the same time permit its easy removal.

The beads 27 are constructed as illustrated, particularly in Figures 7and 8. Each comprises a main portion, the under surface of which is cutaway or rabbeted to receive a movable portion 27a, and between suchportions a plurality of springs 27 b are interposed which serve to forcethe movable portion 27a of the bead outwardly, the two parts being heldfrom separation by any suitable fastening device such as screws 270.

As shown in Figure 10, the side members 10 may be grooved and beads 27provided with a. tongue fitting in the grooves. The beads may beremovably held in the grooves by snap fasteners as above described or inany other suitable manner.

In the form of front bead illustrated in Figure 9 a resilient strip ofmetal M takes the place of the movable portion 27 a heretoforedescribed, such metal strip being secured to the inner surface of thebead and being arranged to yieldably press against the side rails 24 ofthe lower sash.

Vhen the front beads 27 are sna )ped or fastened in position, it will bean erstood that the spring pressed portions 27a thereof will bearagainst the front or inner face of the side rails 24 of the lower sash.The springs in the beads will tend to force the inner sash rearwardlyagainst the strips 20 which in turn are forced rearwardly toward therear beads 15 of the frame. By this means, all parts of the constructionare held in tight engagement so as to effectively prevent the entranceof air. But at the same time, the parts are held yieldably in engagementso that in case of dampness or swelling of the wood there is practicallyno danger of the sash sticking in the frame or becoming so tight as toprevent'raising and lowering of the same.

The upper portions-of the strips 20 are preferably provided with acentral bead 33 which serves to space the front and rear sashes of thewindow. The head 33 extends downwardly a distance substantially equal tothe height of the rear sash. In other words, the bead 33 is short enoughto permit the upper or rear sash to be withdrawn or tilted v forwardlywhen the upper sash is lowered in the frame. "Likewise the lower orinner sash can be tilted forwardly or inwardly when the beads 27 areremoved. The position of the sash when thus tilted inwardly isillustrated in dotted lines in Figure 2 of the drawings. By this meansaccess can be easily had to the exterior surface of the windows forcleaning the same.

It is to be understood, of course, that the windows are supported in theusual manner by means of cords34. In the case of the upper sash, thecords 34 are arranged in rectangular notches in the rear corners of theside rails 16 so as to permit the upper sash.

to be easily tilted forward when the same has been lowered. In the caseof the lower sash, the cords 34 are preferably arranged in grooves inthe inner edges of the side rails 24.

In each case the cords arepreferably secured...

to the sash by means of pins or screws 35 inserted in the side rails andaround which the ends of the cords are looped.

To asist in securing an air-tight construction, a resilient packing 36is arranged be-.;

tween the lower rail of the upper sash and the upper rail of the lowersash, either or both of the rails being suitably notched to receive suchpacking. It will be seen that when the front sash is forced rearwardlyas heretofore, described, the front rail 25 will be pressed toward therear rail 18 which will tend to compress the packing and thus maintain atight joint at this point. If desired, a packing 37 may also be placedat the lower inner edge of the lower sash against which the lower rail26 of the lower sash is adapted to press when the sash is lowered.

It is to be understood that my invention is not limited to the exactdetails herein described but that the same is capable of various changesand modifications, and that various features and details therein may bemodified or omitted without departing from the scope of the same as setforth in the appended claims.
